BERT L. VAN OMAN, OI HIGHLAND PARK, MICHIGAN, ASSIGNOR TO L. A. YOUNG INDUSTRIES, INC., OF DETROIT, MICHIGAN.

arms-comma Application filed Augult 22, 1923. Serial No. 658,726.

To all whom. it may concern:

Be it known that I, BERT L.- VAN ORMAN, a citizen of the UnitedISta-tes, residing at Highland Park, county of Wayne, Stateof Michigan, have invented certain new and useful Improvements in Spring-Coiling Machines, 'of which the following is a spec fication.

This invention relates to improvements in spring coiling machines.

My present improvements are especially med b me tor use or embodiment in machines For the manufacture of coiled sprin s such. as are used in beds, furniture, vehic e seats and the like shown in my Letters Patent No. 1,480,796 issued January 15, 1924. Certain features of my improvements are, however, desirable and readily .ada ted for use in other relations.

T e main objects of this invention are First, to provide in a wire spring making machine an improved coiling mechanism.

Second, to provide in a wire spring making machine an improved means for adjusting the coiling mechanism to change the size and shape of the spring.

Thirdfto provide in a s ring coiling machine an improved cut-o mechanism for the formed spring.

Fourth, to provide in a spring coiling machine an improved means for supporting the formed spring while being cut-ofi' or severed from the stock and transferring it to and holding it securely during the knottin" operation.

urther objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention .is clearly, defined and pointed out in the claims.

A structure which is a preferred embodiment of my inventionis clearly illustrated in the accompanying drawing, forming a part of this application, in which:
